Improbable Research

Today’s Headline of the Day appears in the Retraction Watch blog:

Astrophysics retraction trail includes paper that plagiarized another already retracted for… plagiarism

Complementing their postmodern approach to range science, the USDA-ARS, Jornada Experimental Range, Las Cruces, New Mexico, has pioneered the development of the remote-controlled cow. Their directional virtual fencing (DVF™) electronics package is carried by the cows on an ear-a-round (EAR™). The results can be seen here.

Today’s Headline of the Day is from a press release issued by New York Medical College. The headline is:

Research findings show brain injury to soldiers can arise from exposure to a single explosion

BONUS: If you know of a study showing that brain injury to soldiers CANNOT arise from exposure to a single explosion, we would love to hear about it.

BONUS: The Neurocritic has some bones to pick with (1) the press release as a whole, and with (2) the way some news organizations reported it.

A new study builds, in a sense, on the work of 1996 Ig Nobel economics prize winner Dr. Robert Genco [pictured here] of the University of Buffalo. Dr. Genco was honored then for his discovery that “financial strain is a risk indicator for destructive periodontal disease.” The new study is:

“Academic stress as a risk factor for dental caries,” Cynthia Mejía-Rubalcava, Jorge Alanís-Tavira, Liliana Argueta-Figueroa, Alejandra Legorreta-Reyna, International Dental Journal, vol. 62, no. 3, June 2012, pp. 127-31. The authors, at the Autonomous University of the State of Mexico (UAEMex), Toluca, Mexico, report:

“Conclusions: Moderate to high levels of academic stress, younger age and lower salivary flow rate represent risk factors for the development of dental caries in students.”

BONUS: And of course, there’s the possibly unrelated question of sugar, sugar, sugar, sugar

If you like to read about sugar or about aggressiveness, Brad J. Bushman [pictured here] and colleagues have a study perhaps worth some moments of your time:

“Sweetened blood cools hot tempers: physiological self-control and aggression,” C. Nathan DeWall, Timothy Deckman, Matthew T. Gailliot, Brad J. Bushman, Aggressive Behavior, 2011 Jan-Feb;37(1):73-80. The authors explain:

“Aggressive and violent behaviors are restrained by self-control. Self-control consumes a lot of glucose in the brain, suggesting that low glucose and poor glucose metabolism are linked to aggression and violence. Four studies tested this hypothesis. Study 1 found that participants who consumed a glucose beverage behaved less aggressively than did participants who consumed a placebo beverage. Study 2 found an indirect relationship between diabetes (a disorder marked by low glucose levels and poor glucose metabolism) and aggressiveness through low self-control. Study 3 found that states with high diabetes rates also had high violent crime rates. Study 4 found that countries with high rates of glucose-6-phosphate dehydrogenase deficiency (a metabolic disorder related to low glucose levels) also had higher killings rates, both war related and non-war related. All four studies suggest that a spoonful of sugar helps aggressive and violent behaviors go down.”
